Identification of interspecific peach and Prunus sp. hybrids resistant to Plum pox virus infection

Jaroslav Polák, Ivan Oukropec

Plant Protect. Sci., 2010, 46(4):139-144 | DOI: 10.17221/11/2010-PPS  

Interspecific hybrids of Prunus persica, Barier, Fire, Cadaman, GF-677, and Prunus sp. hybrids and selections, MRS, NBS 540-73, and Pumiselect were evaluated for resistance to Plum pox virus. Hybrids were grafted onto trees of a peach cultivar artificially infected with PPV and evaluated for six years for resistance to the virus. The relative concentration of PPV protein was determined by semiquantitative ELISA in June every year. The presence of PPV in peach hybrids was confirmed by IC-RT-PCR in 2007-2008. The presence and intensity of PPV symptoms were evaluated monthly from May to September. The hybrid GF-677 (P. amygdalus...

Analysis of genetic diversity and phylogeny of partial coat protein domain in Czech and Italian GFLV isolates

Aleš EICHMEIER, Miroslav BARÁNEK, Miroslav PIDRA

Plant Protect. Sci., 2010, 46(4):145-148 | DOI: 10.17221/10/2010-PPS  

The genetic diversity of Grapevine fanleaf virus (GFLV) was evaluated in 4 isolates sampled from naturally infected grapevines from South Moravia (Czech Republic) and 2 Italian isolates from Bari (Italy). Conserved regions within sequences in databases were found and new primers corresponding to these regions were designed and tested for RT-PCR amplification of the CP codifying region. After sequencing of obtained amplicons the similarity of isolates was analysed via alignments of sequences and by means of dendrograms

Chemically modified chitosans as antimicrobial agents against some plant pathogenic bacteria and fungi

Entsar Ibrahim Rabea, Walter Steurbaut

Plant Protect. Sci., 2010, 46(4):149-158 | DOI: 10.17221/9/2009-PPS  

The antimicrobial activity of eight chemically modified chitosans against plant pathogenic bacteria of crown gall disease Agrobacterium tumefaciens and soft mould disease Erwinia carotovora and fungi of early blight disease Alternaria alternata, root rot disease Fusarium oxysporum, and damping off disease Pythium debaryanum was investigated. The minimum inhibitory concentration (MIC) of these compounds against the tested bacteria showed that N-(o,o-dichlorobenzyl)chitosan exhibited a high activity against A. tumefaciens and E. carotovora (MIC = 500 and 480 mg/l, respectively). In addition,...

Communities of oribatid mites and heavy metal accumulation in oribatid species in agricultural soils in Egypt impacted by waste water

Hamdy Mahmoud EL-SHARABASY, Ahmed IBRAHIM

Plant Protect. Sci., 2010, 46(4):159-170 | DOI: 10.17221/31/2010-PPS  

The continued use of waste water for irrigation of agricultural fields in Egypt may lead to accumulation of heavy metals in soils and adverse effects on soil-living communities. We investigated responses of oribatid communities to heavy metal contamination in mango plantations irrigated by the Ismailia canal in the Suez region. Mean concentrations of heavy metals determined in irrigation water were considerably above the recommended levels. Concentrations of metals in agricultural soil were however below the permissible levels. A comparison with concentrations of a typical uncontaminated soil in this area revealed that the Ismailia water canal used...

Variability of D2/D3 segment sequences of several populations and pathotypes of potato cyst nematodes (Globodera rostochiensis, Globodera pallida)

Ondřej Douda, Miloslav Zouhar, Eva Nováková, Jana Mazáková, Pavel Ryšánek

Plant Protect. Sci., 2010, 46(4):171-180 | DOI: 10.17221/1/2010-PPS  

Potato cyst nematodes (Globodera rostochiensis, Globodera pallida) remain a key pest in the main potato growing regions of the Czech Republic. Due to difficult direct management and presence of diverse pathotypes attacking different potato cultivars the rapid and reliable diagnostics is of crucial importance. Currently, efforts are aimed at a description of different pathotypes based on DNA analysis. The main objective of this study was to evaluate the homogeneity of sequences of D2/D3 segments of the 28S rDNA gene obtained from 3 populations of G. rostochiensis and 5 populations of G. pallida and estimate their value for...

First report on Monilinia fructicola in the Slovak Republic

Nadežda Ondejková, Michaela Hudecová, Kamila Bacigálová

Plant Protect. Sci., 2010, 46(4):181-184 | DOI: 10.17221/1271-PPS  

The occurrence of Monilinia on stone and pome fruit trees in Slovakia was studied. Commonly distributed species Monilinia laxa, M. fructigena, and American species M. fructicola were determined by the methods used. M. fructicola was identified on the fruits of peach and nectarine imported to our country and on domestic plum fruits as well. To our knowledge, this is the first report on M. fructicola in Slovakia and a new member for Slovak mycobiota.

First Record of Horidiplosis ficifolii Harris 2003 (Diptera: Cecidomyiidae) in the Czech Republic

Jakub BERÁNEK, Ivana ŠAFRÁNKOVÁ

Plant Protect. Sci., 2010, 46(4):189-191 | DOI: 10.17221/53/2009-PPS  

In November 2009 the gall midge species Horidiplosis ficifolii Harris 2003 was detected in the Czech Republic on leaves of an ornamental fig Ficus microcarpa. The insect is native to South East Asia, where it lives on the genus Ficus. No information is currently available on the prevalence of the pest in the countries of its origin. Imported Ficus plants from China into the Netherlands are sometimes heavily infested with the gall midge. In Europe it is also known from Denmark and the United Kingdom. As Horidiplosis ficifolii is a tropical species, no environmental and social damage is expected.
